Cooling system for electrical device

Abstract

The invention relates to a cooling system for an electrical device. The cooling system comprises the electrical device, a gas removal tank, an expansion tank, a pump, a filter and a refrigeration device which are connected through a first pipeline to form an enclosed loop, wherein the refrigeration device comprises a first heat exchanger, a compressor, a second heat exchanger and a throttling element which are successively connected through a second pipeline to form an enclosed loop; the first pipeline is internally provided with a cooling liquid for heat exchange with the electrical device; the second pipeline is internally provided with a refrigerant; and the refrigeration device performs heat exchange with the cooling liquid in the first pipeline and external air through the refrigerant. The cooling system provided by the invention enables cooling of an electrical device to not relay on environment air temperature, overcome the defects in the prior art, reduces working environment temperature of the electrical device, and improves the service life of the devices in the electrical device, therefore, the adoption of high temperature resistant components is unnecessary, and the product cost is also saved.

Description

technical field [0001] The invention relates to the field of electrical technology, and more specifically, to a cooling system for electrical equipment. Background technique [0002] With the development of power electronics technology, the structural design of high-power electrical equipment is becoming more and more compact, which makes the internal heat of electrical equipment more and more concentrated, and the reduction of the internal space of electrical equipment also makes it more difficult to dissipate heat. In recent years, water-cooling heat dissipation technology has developed rapidly. It not only surpasses heat dissipation methods such as air cooling and heat pipes in terms of heat dissipation effect, but also achieves good results in noise control and application environment adaptability. Therefore, in the heat dissipation of high-power and high-power-density electrical equipment products (including frequency converters, reactive power compensation devices, win...
